BCG-elicited mouse peritoneal macrophages were separated into three subpopulations by counterflow centrifugal elutriation. The three subpopulations were characterized on the basis of the level of a protein cross-linking enzyme, tissue transglutaminase. Subpopulation-3 consisted of large cells (greater than 95% esterase positive and greater than 90% viable)(More)
Glycopeptidolipid (GPL) antigens which are associated with the superficial L1 layer of Mycobacterium intracellulare serovar 20 were labeled with radioisotopes by means of internal labeling techniques and used in macrophage uptake and retention studies. The use of tritiated alanine and phenylalanine allowed the incorporation of label into the GPL invariant(More)
